HOUSING.

Application filed June 21, 1924. Serial 110,721,608.

This invention relates to housings, and more particularly to housingscomprising a plurality of cooperating members or sections. I

An object of the invention is to provide a housing comprising aplurality of sections which can be quickly and easily brought into andout of their functionally operative positions. v

A further'object of the invention is to provide a housing comprising aplurality of cooperating sections of which one section is adapted tohold the other in an adjusted position.

A still further object of'the invention is to provide a housingcomprising a plurality of sections wherein a displacen'lent of onesection will be accompanied by a displacement to a dill'erent degree ofthe other section.

A. housing embodying one form of the invention is employed as a guardupon a machine adapted to insulate wires which are to be used aselectrical conductors. The guard is associated with the servingmechanism of the machine and comprises aplurality of complementarysections pivotally mounted upon axes disposed at an angle to each other.This construction enables the opera tor to bring the sections into andout of positions wherein they enclose the serving mechanism, it beingnecessary to open the housing when the supply of insulating ma terial isto-be replenished. Means is provided for operatively connecting thesections so that displacement of one of the sections is accompanied bydisplacement to a larger degree of the other. Thus, the operator needonly displace one of the sections when the housing is to be openedorclosed. The section opened. to the larger degree is adapted to hold theother section in its open position.

Other objects of the invention will become apparent as the detaileddescription pro grosses, reference being had to the accompanyingdrawing, wherein Fig. 1 is a front elevation of a paper insulatingmachine wherein a guard embodying the invention is provided;

Fig. 2 is an enlarged fragmentary front elevation of a paper insulatingmachine, several means or parts of the guard being shown in changedpositions;

Fig. .3 is a plan view of a guard embodyingtheinvention, and

Referring to the drawing the reference character 10 designates in itsentirety a housing embodyingthe invention, the housing being employed asa guard upon a paper insulating machine of a well-known type. The paperinsulating machine comprises a frame 11 wherein a supply reel 12 andatake-up reel 13'are rotatably journaled. Suitable means (not shown) areprovided fordriving the take-up reel 13 so that it will draw the wire tobe insulated from the supply reel 12, the wire being drawn through aserving mechanism indicated at 14: and over a capstan 15. In thisinstance, the serving mechanism 14; is adapted to apply paper in ribbonform to the wire as it is advanced through the'serving mechanism, theserving mechanism beingrotated at high speed during the operation of themachine. The serving mechanism comprises a disk 16 which supports anarrow rollof the paper to be applied to the wire. It is of'coursenecessarythat the supply of paper upon the disk 16 be replenished fromtime to time and for this purposea plurality of narrow rolls of paperindicated at 17 rest upona bracket 18 from which position they may belowered one at, a time to thedisk 16. However, be-

cause of the high speed'a-t which theserving mechanism rotates, it isadvantageous to have it covered during the operation of the machine sothat the operator cannot come in contact with the rapidly rotatingmechanism. At the same time, it is desirable that the housing be soconstructed that the operator can quickly and easily bring it out of itsprotecting position to permit a renewal of the supply of paper upon thedisk 16.

The aforementioned housing or guard 10 afliords ample protection to theoperator and does not impede the efforts of the operator when the supplyof paper upon the is being replenished. The housing or guard 10comprises a plurality of sections 20 and 21 rigidly secured to aplurality of shafts 22 and 23, respectively. The shafts 22 and 23 aredisposed at rightv angles to each other and are rotatably journaled in aplurality of disk 16 bearings 24 mounted upon the frame 11 of theinsulating machine. Rigidly secured to the shaft 22 1s a bevel gear 25whichmeshes with a bevel gear 26 secured to the shaft C m v 1. 2., thegears being so proportioned that angular displacement of the section 20-is accompanied by a larger angi-ilar displacement of the section 21. Thesection 20 is provided with a handle 27 whereby the operator may bringthe section into the position wherein it is shown in Fig. 2, when thesupply of paper upon the disk 16 is to be renewed. This displacement ofthe section 20 is accompanied by a larger displacement of the section 21which is brought into the position wherein it is shown in Fig-4:. Thesection 21 is provided with a lug 28wh'ich functions as a stop andlimits the displacement of the sections 20 and 21 with respectrto theirclosed positions, as

- shown in Fi 4 the 111 28 is ada Jted to engage the frame 11 when thesection 21 has been brought into a position wherein it tends to rotatein a clockwise direction and to hold the section 20 in its openposition. The arrangement is such that the section 20 need only bebrought to an upright position when the guard isopened in which positionit does not interfere with the wire trained between the capstan 15 andthe take-up reel 13. This arrangement is advantageous in that themachine can bebuilt compactly, thus facilitating the task of theoperator who generally handles five machines placed side by side andoperated from a common drive shaft.

It will be noted that each of the sections 20 ncsesaa ing advancedthrough the serving mechanism nism, and means including co-operatingbevel gears for separating andwithdrawing all of the sections from theirenclosing positions to permit access to the mechanism when one of saidsections isvwithdrawn.

2. A housing for mechanism comprising a hinged section having a cut-outsector to surround a projecting portion of the mechanism, a secondsection hinged at rightangles thereto and having a'similar sector, meansfor aligning the sectors to form an aperture in the housing when closed,andmeans including co-operating bevel gears for moving one of thesections whenthe other section is moved.

8. A housing comprising apair of substantially semi-circular sectionshaving depending portions adapted to shield an operating mechanism,meansfor mounting said sect-ions on axes at rignt angles to each other. 7

and means interconnecting said means responsive to the movement of onesection to cause the movement. 01 the other section through a greaterangle.

4. A; housing comprising a pair of sections each of said sections havingan" arcuate flange and a substantially flat top wall mem*- bers on whichsaid sections move, and means includinggears interconnecting saidmembers responsive to the movement of one section for causingthemovement of the other section.
